For half a century, CHA has developed innovative, environmentally-sound, and cost-effective wastewater treatment systems to meet increasingly stringent regulations. We use conventional as well as innovative treatment technologies for industrial and domestic wastewater treatment. Our wastewater management services include a full range of engineering and support services for these systems, from initial planning through start-up and ongoing operational assistance.

CHA is also a leading expert in collection systems and wet weather flow. We have assisted our many clients in constructing new gravity sewer lines, pump stations, and force mains. We have helped numerous communities with wet weather flow issues such as Rainfall-derived Infiltration and Inflow (RDII) modeling, sewer system evaluation surveys, infiltration and inflow studies, sewer system rehabilitation, and equalization basin design.
